The Tata Harrier is currently available with a 2.0L Kryotec diesel engine that produces 140 PS and 350 Nm of torque. This engine is basically a rebranded 2.0L MultiJet II unit made by FCA. The 170 PS will likely deliver the same amount of torque. It will be BS-VI compliant right from the get-go. Trademark filings accessed by IAB suggest that it will be branded 'Kryotec170'. FCA will use this engine in India for one of its own models first - the Jeep Compass Trailhawk, which will go on sale in by July this year. The Tata Buzzard (to be renamed at the time of launch) will get this engine by the end of this year, and then the Tata Harrier.

Tata Motors offers the 140 PS 2.0L diesel engine in the Harrier with only a 6-speed manual transmission. However, it is planning to introduce a 6-speed automatic transmission sourced from Hyundai, and it may do so along with the 170 PS 2.0L diesel engine. The new options could be introduced around the same time when the 5-seat C-SUV completes its first year in the market (January 2020) or a little later. In the coming months, another development could be the commencement of exports as well.

The Tata Harrier is based on OMEGA (Optimal Modular Efficient Global Advanced Architecture) platform derived from Land Rover's D8 architecture.
